Tlwy object of this device is to permit the liol. 3l to llo willirlrwuora @ompleliun of the will. the pipe or Sleeve 50 remaining in che wall.permanently, and being morturrival uli.

The member is then screwed in its place in the guides sothatI by the same method, working from the opposite side. this guide(30, 28) may be toreol from the wallj The cuppin of the lug 3?) preventsinjury to the threat and the bevel on the threaded washer 3) and lug 33gives a tight joint and permits of a shorter and heavier pipe sleevebeing used :is may be desirable if these cross members are to be usedtemporarily to support si'ali'old or runwaiY planks. At the top of thesechannels :2S are cross connecting angle members 3:2. bolted to channelsb v bolts 55 and supporting and fastened to two, trans verse membersfrom which the mold is suspended by rope or chain pulley blocks '2.3.The framed guides 28 are braced by bolted cross steel angles or flats 3ito a preerected sratlold, or to stakes driven in the ground. or by sway'bracing For considerr able heights. The framed guides (28, 33, 530. 3l.51. 32) are previously assembled, erei'ted as a unit. and when braced asdeseiibed and in eminection with the transverse member. a'iord anabsolutely automatic plumb and alinement for the mold members and wall.

The tl anges of the channel members 28 of the framed guide project intothe Wall and are heavily greased to prevent adhesion, but the supportoi' the concrete at the sides of the tianges oi' the members 28 givesgreat stiffness particularlyv in the line of the strain caused by theweight of the mold members, permitting a comparatively light section tobe used The small groove left on their withdrawal is mortared up, whenabove the grade. or used as a. natural termination for tarwaterproofing. when below the grade at the corners. as hereinafterdescribed.

molding device such as is shown in Figs. 1. Q. l, 6. T. S. 11. 12, 13,14 is applied to the opposite sides of the framed guides. This moldingdevice consists of two fiat members or sides madey 'up of tWo sets ofplanks. l, 1, which are short, narrow members etc.. positionedvertically. and lonn gitudinal members il. 2, etc.. running the wholelength of the side mold; the grain of each set of members being at rightangles to the other set. These sets l and Q, are securely bolted. nailedor screwed together,

i and at top and bottom have heavy sti'ening angles 4 and 5 to whichthey are rigidly attached by screws or bolts. These side members rangefrom ten to twenty feet in length and are fi om two to four feet indepth. such lengths or depths being stock sizes and used as conditionsrequire. The inner faces of these side molds are lined with sheet metal3, preferably zinc. This arrangement of the wood strips 1 and 2 acts toprevent shrinkage and expansion as the direction of movement of swellingor shrinkage for each set opposes that of the other. Longitudinalstiffness is obtained by the heavy steel angles 4 and 5. and greatresistance to warping, deflections, etc., is obtained, as the shortpieces l span from angle to angle and 7 are held rigidly at thosepoints.

The upper angle members 4 have sets of holes in them (30. to receivebolts by which members 21 of T-cross section are secured. The projectinglegs of these T members act as a bearing to a roller member which issecured from sliding movement by threads and nuts at its extremities.lvnder each pair of these rollers passes a yoke member consisting of around bar 22, preferably holg5 low, through which tivo eyebolts pass, achain member ".24 connecting these eyebolts 2G to the pulley member 25.A num-- ber of sets of holes G0 in the angle member 4 permit of theposition ot" the T members 21 and rollers and yoke and pulley mem* bersbeing shifted to facilitate construction of windows or other openings inthe Wall. The function of the roller members 23 is to allow easy,frictionless movement of the heavy outside, mold members (1, 2) awayfrom and toward the wall. thus preventing slipping, jarring, orvibration against the green wall during the process r t"-dise1igagementand resetting. The peculiar function of the yoke member is to afford asingle een tral application of power in hoisting, anda connecting meansot' support by which th\` sid molds are kept on the saine vertical lev lduring hoisting. and readily adjusted in relation thereto.

Hoisting ropes 62 are rigged through pnlleys hung from the supportingmember 35, passing also through pulleys 7.45 fastened to the hoistingyokes "2G, Jf) finally connecting with the drum ot' some hoisting devire of any desired style.

At the ends ot' the side members are angle members with holes at the top(see Figs. 1. 2, 5) and bottom 7. through which run iron rods 8 whichsupport and brace an end, closing member 27 for use where the sidemembers are not continuous, end to end. abutting with a small clearanceinterval on the guide-frame members. These end pieces 2T have, a shortangle piece 9 secured in the center at or near the top. To disengage,when a section of wall has been cast, the bolt 8 is wedged up and intothe adjoining part of the hole 7 in the side angles 6. The lower bolt 8is then pulled out, allowing the end member 2T to swing clear at bottom.being supported on the rod by angle 9,
